Firefighters pulled a pregnant woman alive from the rubble of the collapsed three-story building in Brooklyn on Thursday. 

She was lifted out on a stretcher and rushed to the hospital in a waiting ambulance, Fox News reported. 

At least eight people have been killed in the incident. Firefighters and police continued to dig through the rubble on Thursday, using dogs to help locate survivors. In addition to the eight deaths, 17 people have been hospitalized with injuries, including four who are in critical condition. 

The building is a mixed-use structure with apartments situated over ground-floor commercial space. 

The cause of the collapse is under investigation. New York City’s buildings commissioner, Ahmed Tigani, pointed out that construction workers were excavating an empty lot next door for a new building when the building fell.
